Actually, if you are deriving the GtkComboBox and trying to access the
GtkCellLayout interface from my_derived_combo_box_init(), the problem
is that you have not waited for the combo box to completely be built yet
(in a sense, you can say that at _init() time, the parent GtkComboBoxClass
has just not finished becoming a GtkCellLayout yet).
If this is the case for you, just move the code that accesses the GtkCellLayout
iface from my_combo_box_init() to my_combo_box_constructor() and you will
be fine (i.e. at that point you know that the parent object has
finished initializing
completely).
I know others will disagree and throw pizza at me, but that's alright
(I like pizza).
